SPECIFICATION forming part of Letters Patent No. 791,632, dated June 6, 1905.
Applioationiled May 31, 1904. Serial No. 210,557.
To @ZZ whom it may concern,.-
Be it known that I, WILLIE O. LINDGREN, a citizen of the United States, residing at Litchville, in the county of Barnes and State of North Dakota, have invented certain new and useful Improvements in Ohurns, of .which the following isa specification.
This invention relates to churns; and among the objects in view is to provide a churn which shall be comparatively simple and inexpensive in its general construction.
A further object is to provide an improved construction of churn-body and dasher by which butter may be quickly produced, and with the described objects in view.
Theinvention consists in the novel construction, arrangement, and combination of parts,
as hereinafter fully described.illustrated in the drawings, and pointed out in the appended claims.
In the drawings, Figure 1 is an elevation of a churn embodying the invention. side elevation of the churn. Fig. 3 is an elevation ofthe dasher detached. Fig. 4 is a plan view of the churn-body. Fig. 5 is a vertical sectional view of the churn-body.
1 indicates a suitable supporting-framework adapted to support the operative parts of the churn. Y
2 indicates the churn-body, which, as shown, is of trunco-conical shape, though it may have a cylindrical shape. The body is provided with trunnions 3, which are removably seated in open bearings 4, secured to the uprights of the framework, whereby the body may be tilted for the purpose of enabling the `dasher and contents to be readily removed and also to enable the body to be lifted from its bear-' desired purpose. I
For maintaining the churn-body in proper position during the churning operation I proings and removed from the framework for any -vide a bent metallic strip, plate, or lug 6, se-
Fig.2 is a ribs 10 of triangular shape in cross-section. These ribs are adapted to coperate with the' arms or bladesA of the dasher, presently described, for the purpose of causing the cream to be agitated or churned more quicklyl and eiiiciently than if' said ribs were not provided. y
The number offribs may be varied.
l2 indicates the dasher, the same comprising the central'hub or shaft 13, provided at the arms 15. The general shape of the dasher should correspond to that of the churn-body, within which latter it is adapted to operate, and therefore in. the present instance it is of conical shape, and the arms or blades 16 should be so positioned that their path of movement when the dasher is rotated would be close to the ribs to thus cause the cream to be thrown against the ribs `by the blades.
The means for rotating the dasher comprises a gear-wheel 20, journaled in a bearing secured to one of the uprights 5 and provided with an operating-crank 21. wheel 2O meshes a smaller gearwheel 22, mounted upon the outer end of a shaft 23, which is mounted in said upright 5 and a bearing-block 24. The inner end of the shaft is provided with a bevel-pinion 25, which gears with a bevel-pinion 26, lmounted upon a vertical shaft 27 whose upper end has a bearing in the cross-piece 28 of the frame and which With the gear' passes down through the cross-piece 29 and projects somewhat below the latter. Any other arrangement of gearing for imparting rotation to the shaft 27 may be employed.
Inasmuch as the churn-body is adapted to be tilted, it is necessary that the connection between the shaft 27 and the dasher should be a separable one, and any desired construction which will `permit of the dasher being detached from the shaft 27, which imparts rotation to the dasher, may be employed. vIn the present instance I provide the upper end of the dasher-shaft with a slot 30, within which is litted a plate 31, secured within the slot by .pins 32. The plate is adapted to detachably IOO mounted on the shaft 27, which collar when slipped down over the end of the plate 3l prevents the latter from working out of the slot 33 in the churning operation. By slipping the collar upwardly to free the upper end of plate 31 the latter is free to move laterally out of the slot 33 when the churn-body is oscillated upon its pivots.
What I claim, and desire to secure by Letters Patent, is-
1. In a churn, the combination with a supporting-frame, of a body portion journaled in the frame and adapted to be tilted, a dasher rotatably mounted in the body, said dasher having a central hub or shaft provided with a slot at its upper end, a vertical shaft mounted in the frame and provided at its lower end with a slot, a plate secured in the slot of the dasher-shaft and adapted to removably engage within the slot of the said vertical shaft, a collar slidingly mounted on the vertical shaft, a lug secured to the churn-body, a bracket secured to an upright of the frame and having a slot within which the lug is seated, a pin passing through alined perforations in the ears of the bracket and the lug and means for rotating the last-named shaft.
2. lIn a churn, the combination with a supporting-frame, of a body portion journaled in the frame and adapted to be tilted, a dasher rotatably mounted in the body and comprising a central hub or shaft, arms extending through the shaft and arms or blades joining the outer ends of the arms, the said central shaft having a Slot at its upper end, a vertical Shaft mounted in the frame and provided at its lower end with a slot, a plate secured in the slot of the dasher-shaft and adapted to removably engage within the slot of the said vertical shaft, a collar slidingly mounted on the vertical shaft and means for rotating the last-named shaft.
In testimony whereof I aiix my signature in presence of two witnesses.
